Are you heating the ball side with a RHP, and that is heating the cage, or is it belly heat? You can always unplug the RHP if that is the case. It doesn't have to be exactly 85 on the hot spot.
Both sides of the cage are heated by separate RHPs... I can't unplug the one of the Ball cage because it'll get too cold... but this causes the grayband side to have a low of 83...
